In the extreme northern region, a cold world of ice and snow.

The chilling wind howled and swept across the frozen land, causing snowflakes the size of grinding discs to fall continuously. Soon, a thick layer of snow, about several zhang deep, accumulated on the ground, covering everything beneath it.

This place is not suitable for ordinary humans to survive. It is a primitive area where no one has set foot for millions of years, and only a few powerful exotic beasts and spirit birds roam. However, deep within the layers of ice and snow, there are still rare and precious mineral veins buried.

At this moment, with the Heavenly Boat Tower as the center, a golden light curtain with a diameter of thousands of zhang enveloped the opened rift in the sky, keeping the snowflakes and cold outside.
